Borrowed from the R3, the R6 Mark II's upgraded processing suits the multimedia nature of the camera. Capable of processing high speed bursts as well as high-res 4K video, the DIGIC X supports up to 40 fps continuous shooting with a silent electronic shutter or 12 fps with a mechanical shutter, with AF and AE readings before each frame. There is also a 30 fps RAW Burst mode, which offers pre-release capture to record moments that happened up to 0.5-sec before you press the shutter.
Also, improved processing leads to improved low-light performance, with the sensitivity range now extending from ISO 100-102400, and expandable to ISO 204800 for working in very difficult lighting conditions.

Beyond stills, the R6 Mark II's sensor also offers high-res UHD 4K 60p internal video using the full width of the sensor and the ability to work with 10-bit sampling with Canon Log 3. A 6K recording area can also be used for oversampled 4K shooting at 30p for improved sharpness, reduced moiré, and lower noise. And, for slow-motion playback, 180p recording is supported at up to Full HD resolution.

HDR-PQ recording is possible, too, for in-camera HDR production and external recording, via the micro-HDMI port, which supports a clean 6K output at up to 60 fps. Also, unlimited recording times are possible, too, and the R6 Mark II features both mic and headphone ports, as well as a multi-function shoe for wide accessories compatibility.

Using the micro-HDMI port, raw video recording is possible when paired with a compatible external recorder. ProRes RAW up to 6K 60p is possible using the full width of the sensor as well as 3.7K raw recording with a crop.

An In-Body Image Stabilizer (IBIS) corrects up to 7 stops of unwanted camera shake when shooting handheld, helping to shoot handheld in low-light conditions and reduce shake when recording videos. This 5-axis system can be also used in conjunction with lenses featuring optical image stabilization to compensate for up to 8 stops of camera shake depending on the specific lens in use. Additionally, Movie Digital IS uses the optical and sensor-shift stabilization methods along with digital IS to help acquire steadier footage while moving.

Wired and wireless connectivity options are available, allowing for multiple methods of transferring photos and videos, as well as for remotely controlling the camera.

• USB-C 3.2 Gen 2 port for in-camera charging and file transfers; this port also enables using the camera as a Full HD 30p webcam with support for UVC/UAC protocols
• 3.5mm headphone and external microphone ports
• Micro-HDMI port for working with an external recorder
• Bluetooth and 5/2.4 GHz Wi-Fi for wireless transfers and remote camera control from mobile devices

An update to a conventional hot shoe, the Multi-Function Shoe adds a row of pins at the front of the design to permit greater accessory functionality as well as provide power to select accessory types that traditionally rely on separate batteries. This updated shoe is compatible with select accessories, including the EL-5 Speedlite, ST-E10 Speedlite Transmitter, DM-E1D Stereo Microphone, and AD-P1 Smartphone Link Adapter, as well as the AD-E1 Multi-Function Shoe Adapter to provide compatibility with legacy shoe-mounted accessories.
